HOW THE VISUALIZER WORKS
b
a
A light projector (b) inside the Wolfvision Visualizer projects
the light via a mirror inside the unit and a mirror on the reflector
head onto the working surface. The video camera (a) inside the
unit scans the picture where the light falls.
The optics of the camera and the light projector are synchronized.
This means that when the size of recording area is increased or
decreased with the ZOOM-keys (#15,#16), the size of the
illuminated area on the working surface is also increased or
decreased.
Thus the illuminated area on the working surface always indicates
where the camera scans the picture. (In fact, the scanned area is
fractionally smaller than the light field.)

BASIC PREPARATIONS
1. Press the release for the arm (#11) and simultaneously pull the arm upward. Make sure that the arm is
extended to its full length.
2. Connect the power cable to the unit (#36) and plug it in.
3. Connect a control monitor (if required) to the Preview video output (#31).
4. Connect a large viewing monitor or a video projector to the Composite video output (#32), the Y/C output
(#37) or the RGBS output (#40). These outputs can be switched on and off with the IMAGE keys (#21,#22)
of the control panel.
For live image projection we highly reccomend using the Y/C output (#37). The picture quality (especially
the resolution) is much better than with the Composite video output (#32). The picture of the Y/C output even
looks a bit sharper than the picture of the RGBS output, as the signal passes a sharpness enhancer. For signal
processing we reccomend using the RGBS output (#40), as this is the original (unprocessed) signal.
The RGBS output also offers the best color reproduction.
5. Turn the main power switch (#34, on the back of the unit) to "I". The red power indicator (#29) on the
control panel indicates that power is supplied.
6. Press the POWER on key (#28) on the control panel. The Visualizer now runs the "factory setup"
(=automatic focusing of an A5 format on the working surface) during which the green LED light (#30)
is flashing. As soon as the green LED light stays illuminated you can start working with the Visualizer.
